The vote breakdown in Ohio’s special election this week amplified a trend that's been building in the suburbs during the Trump era — and illustrated how the traditional Republican path to victory has been upended in key congressional districts.

Deep suburban antipathy toward President Donald Trump has turned the old GOP electoral coalition inside-out in many areas in 2017 and 2018 — like Ohio’s 12th District, which for two decades sent former Rep. Pat Tiberi to Congress on the back of his popularity in the Columbus suburbs. His anointed successor, Republican Troy Balderson, took a different path to a small special-election lead, instead building on Trump’s rural strength while Democrat Danny O'Connor cut deeply into Tiberi’s old base.
